Mobil Delvac™ Extreme FE 10W-30 diesel engine oil with FA-4 identifier

Mobil Delvac™ Extreme FE 10W-30 is a synthetic, high-performance diesel engine oil that helps extend engine life while providing long drain capability for modern diesel engines operating in extreme conditions. It meets or exceeds the new API FA-4 specification for fuel-efficient engine oils, as well as key original equipment manufacturer (OEM) requirements.

Developed in close collaboration with major OEMs, Mobil Delvac Extreme FE 10W-30 engine oil is recommended for use in the extreme applications and operating conditions found in the on-road trucking industry. Its boosted formulation provides:

  • Potential to improve fuel economy*
  • Exceptional oxidation stability
  • Excellent soot and viscosity control

Mobil Delvac Extreme FE 10W-30 engine oil should only be used where an API FA-4 oil is recommended by the OEM. Before using this product in an engine, users should consult recommendations as shown in the owner's manual or other service bulletins.

Mobil Delvac Extreme FE 10W-30 engine oil is recommended by Exxon Mobil for use in:

  • The latest heavy-duty diesel engines operating in extreme applications, where API FA-4 is recommended by the engine builder/OEM
  • Engines equipped with emission control systems, including exhaust after treatment systems
  • On-highway applications operating in both high-speed/high-load conditions and short haul pick-up/delivery

*Meets API FA-4 specification.
Based on an analysis of Volvo T-13 engine test results.
